Thank you for your prompt reply and the link π
Yes, i know these Signs, i have a lot of them, in black and in white with an arrow on it.
We use this to mark the MSR, CP, POL point...... and so on.
But i canΒ΄t remember encrypted unit numbers, for this is eg B196 is a part of the RLC.
I Know the route marker with a bell on it and arrow for route BELL on the Autobahn or streets.
Is eg B196 a short for the UIN ? π€
Best
